ADX Trend Strength Leaf_West style

This is a slightly different way of plotting ADX used by Leaf_West at http://tradingwithleafwest.net/. The criteria for plotting this version of ADX are described in the Educational Info pdfs on the Website.
This is my attempt to replicate Leaf_West's presentation of ADX .
Use of the indicator is described in detail in the Educational info pdfs: http://tradingwithleafwest.net/.
I have used ADX (8) and DMI(9) for a best fit.. Leaf's methods evolve as time goes on and
The BATS data feed has the usual issues affecting the plots, a realtime data feed is the way to go. Credit for the original ADX and DMI script goes to Greeny

study("Trend Strength/ADX Leaf_West style", shorttitle=" Trend Strength ADX LW")
LWadxlength = input(8, title="ADX period")
LWdilength = input(9, title="DMI Length")

dirmov(len) =>
	up = change(high)
	down = -change(low)
	truerange = rma(tr, len)
	plus = fixnan(100 * rma(up > down and up > 0 ? up : 0, len) / truerange)
	minus = fixnan(100 * rma(down > up and down > 0 ? down : 0, len) / truerange)
	[plus, minus]

adx(LWdilength, LWadxlength) => 
	[plus, minus] = dirmov(LWdilength)
	sum = plus + minus
	adx = 100 * rma(abs(plus - minus) / (sum == 0 ? 1 : sum), LWadxlength)
	[adx, plus, minus]

[ADX, up, down] = adx(LWdilength, LWadxlength)
LWADX= (ADX-15)*2.5
adxcolor= up>down?green: red
plot(LWADX, color=adxcolor, title="Trend Strength")
plot (LWADX, color=adxcolor , style= histogram, linewidth= 4)

plot(0, color=black, title="Chop Zone")
plot(20, color=green, title="Mendoza Line", linewidth=1)
plot(100, color=red, title=" Extreme Zone", linewidth=1)
looks interesting
@marax, It is but the method should be used in conjunction with other techniques. I have sent you some info through the TV message system.
Leaf_West's current blog site is http://charts-by-leaf.com/. Please visit his site to download current educational material and read his analysis. Leaf's has detailed and insightful analysis, his ideas continually evolve (although the tried and true ideas remain the same). I recommend following his site and reading his blogs to add a new dimension to your technical analysis. I will update or add to my Leaf_West scripts if I see something new that I think I can do justice to. I have attempted to replicate several of his scripts to make it easier to follow his thinking and to see for yourself how the ideas work in your own analysis.
Message me if you want Leaf WestPdfs. I can give you a dropbox link for downloading the info

Leaf West's website has shut down. He has switched to commenting/educating through Twitter. His educational PDfs are no longer available. I do have some his pdfs if you are interested in reading how Leaf_West intended to use his indicators message me. I can easily send the info via email. I am sure there are other ways available too.
